Adamantine armor deflects iron bolts!!!
edit: in fact Adamantine and Steel armor now are impervious to bolts. (all tests done with Adequate skill)
Adamantine armor: impervious to any bolt, at any range (plate deflects all the bolts, mail turns the damage to blunt)
Steel armor: impervious to any bolt, at any range(plate deflects all the bolts, mail turns the damage to blunt)
Iron armor: It is always penetrated by steel. Iron bolts cause blunt damage even through plate.
Didn't test other kinds.
I have done my own testing, posted
here, which confirms these results. One further point - while steel mail does convert edged to blunt, it is *not* totally effective at preventing serious injuries, while adamantine mail is. Hits against body parts protected by steel mail will frequently result in chipped or broken bones, or jamming of parts through other parts, all of which tend to incapacitate the victim (due to pain). I'm not sure why adamantine mail is more effective, but this definitely bears further investigation, as I think if anything adamantine was less effective as mail previously.
I also agree that this is meant to be a rough, temporary system, and that it is exceptionally good as such. Adamantine provides nearly complete protection, steel very good protection, and everything else nothing. I think historical arguments would support that nothing less strong than steel could stop a bolt/arrow from a powerful bow. I would eventually like to see a system where lesser armors could stop hits if they occur at a glancing angle, or something like this, but for now I think this is great! I am working on doing a complete characterization of the new combat/armor system, and will
post results as they become available (I have my computer automated to run large-scale tests in the arena, but this still takes time). This should hopefully allow people who aren't totally satisfied with the current system to mod it as desired, although I think the number of dissatisfied people will be far lower with these new changes. Also, if anyone is interested in helping run tests or has suggestions for what should be tested, I would greatly welcome help.
